TPS82085: High output ripple

Part Number: TPS82085

Hi Team,

My customer reports that when loaded the deviceabove a 2.5A load the ripple starts to increase until it gets to about 200-300mv at 3A load . Do you know why this would be ? 

It gets worse during extreme temp and stars at 2.3 A.

I've seen on another thread that a higher input capacitance is needed.

Can you please elaborate and let us know how much input capacitance is required ?

Best regards,

Nir.
